Be it known that I, RICHARD B. CAv'ANAGH, a citizen of the UnitedStates, residing in Washington, in the District of Columbia, have 5invented certain new and useful Improvements in Golf-Balls, of which thefollowing is a specication.

This invention relates to golf-balls; and its object is to produce atlow cost a durable ball 1o which has good flying power.

In the accompanying drawings, Figure l illustrates, partly in section, agolf-ball made in accordance with my present invention; and Fig. 2 showsanother form of center piece.

Upon a center piece A, preferably of soft rubber and preferably having acenter A of metal or other hard material, I apply a thick sphere B,consisting of paper or paper-pulp. The sphere B is highly compressed andmay, zo if desired, be formed in segments and then.

united under great pressure upon the center piece A. I then apply agutta-percha shell C under heat and pressure in such a manner as to holdthe iilling B under high com- 2 5 pression. At the operation of applyingthe shell C the gutta-percha is softened by the heat, and the paperiilling Bis caused to join firmly to said shell, practically all overthe interior surface thereof, thereby making the 3o ball of good flyingquality and great durability.

AtFig. 2 is illustrated a center piece D, which may be used instead ofthe soft rubber A and which consists of a mixture of 'Serial No.117,606. (No model.)
